# Objective - Changes the default clear color to match the code block color on Bevy's website. ## Solution - Changed the clear color, updated text in examples to ensure adequate contrast. Inconsistent usage of white text color set to use the default color instead, which is already white. - Additionally, updated the `3d_scene` example to make it look a bit better, and use bevy's branding colors.
